Definitions

  • the invention relates to a steering mechanism for transport equipment, which steering mechanism can be used, for example, in a truck or in a trailer of a truck.
  • the publication presents a transport equipment body provided with a plurality of wheels, of which at least one is a drive wheel, and a transport equipment centre articulation which divides the body of the transport equipment into a front body part and a rear body part such that the transport equipment further comprises a trailer connectable to the body of the transport equipment by a fastening articulation.
  • a trailer comprises a trailer body, a trailer transport box, and a plurality of wheels, of which at least two wheels are arranged to be steerable wheels.
  • the transport equipment should be designed such that it can conveniently move and turn in relatively narrow and even limited spaces.
  • the steering mechanism according to the invention is characterized in that the steering knuckles in the steering mechanism are fastened by articulation to the body of the transport equipment, and that hub pieces fastened by articulation to the steering knuckles are pivotable with respect to the steering knuckle to which they are fastened, and that the hub pieces are pivotable by means of actuators connected to them, and further that the steering knuckles are pivotable by actuators arranged in them to a desired angle so that for steering the transport equipment when either of the steering knuckles pivots about the respective articulation provided in the body, the hub piece in the pivoting steering knuckle simultaneously remains unpivoted with respect to the steering knuckle to which it is fastened by articulation, wherein simultaneously the other steering knuckle remains unpivoted in its articulation provided in the body, and the hub piece therein thus pivots with respect to the steering knuckle to which it is fastened by articulation.
  • the present invention provides several advantages, which become more apparent in the detailed description.
  • the steering mechanism according to the invention in spite of the large turning angle of the wheels, space for the body is amply provided between the wheels; in other words, even if the turning angles of the wheels may be large, the wheels still do not require a lot of space. For this reason, there is no need to make the body structures larger (in other words, to modify the body structure in order to make the turning angle of the wheels larger) for increasing the turning angles of the wheels.
  • FIG. 1 a shows a steering mechanism according to the invention in a perspective view.
  • FIG. 1 b shows the steering mechanism according to the invention in a top view (when driving straight ahead).
  • FIG. 2 a shows the steering mechanism according to the invention in a top view when turning to the right.
  • FIG. 2 b shows a perspective view of the steering mechanism in the situation of FIG. 2 a.
  • FIG. 3 a shows the steering mechanism according to the invention in a top view when turning to the left.
  • FIG. 3 b shows a perspective view of the steering mechanism in the situation of FIG. 3 a.
  • FIG. 1 a shows the steering mechanism according to the invention in a perspective view, and in a corresponding manner
  • FIG. 1 b shows the steering mechanism according to the invention in a top view, the steering mechanism being arranged in the body of the transport equipment.
  • FIGS. 1 a and 1 b illustrate a situation in which the transport equipment is driven straight ahead, but it is obvious that the steering mechanism also works in a situation of reversing, that is, when the travel direction of the transport equipment is initially opposite to that shown by an arrow in FIG. 1 a.
  • the steering mechanism according to the invention particularly intended for use in transport equipment, such as a truck or a trailer of a truck, comprises at least one steering knuckle 4 , 5 on each side of the body 3 of the transport equipment, a hub piece 6 , 7 being fastened by articulation to the steering knuckles, and further, wheels 8 , 9 of the transport equipment being fastened to the hub pieces in the steering knuckles, as shown in FIG. 1 b .
  • FIG. 1 b According to FIG.
  • the steering knuckles 4 , 5 are fastened to the body 3 of the transport equipment by means of articulations 14 and 15 , and the hub pieces 6 , 7 fastened by articulation to the steering knuckles are pivotable to a desired angle with respect to the steering knuckle to which they are fastened; that is, as shown in the figure, the hub piece 6 is pivotable with respect to the steering knuckle 4 , and the hub piece 7 is pivotable with respect to the steering knuckle 5 , respectively.
  • the rotation of the hub pieces is provided by means of actuators 10 , 11 , such as hydraulic actuators, connected to them, and in a corresponding manner, the steering knuckles are also pivotable to a desired angle by means of actuators 12 , 13 provided in them.
  • actuators 10 , 11 such as hydraulic actuators, connected to them, and in a corresponding manner, the steering knuckles are also pivotable to a desired angle by means of actuators 12 , 13 provided in them.
  • the hub piece 6 in the steering knuckle 5 on the opposite side of the body simultaneously pivots the same angle or a different angle with respect to the steering knuckle to which it is fastened by articulation.
  • the hub pieces 6 , 7 are connected to each other by a set of levers 16 , 17 and 18 for controlling the mutual pivoting of the hub pieces when either of the steering knuckles is pivoted.
  • the hub pieces 6 , 7 comprise a lever arm or they are provided with a lever arm (or a lever-arm-like shoulder) 2 , to which one or more actuators 10 , 11 (as well as the set of levers 16 to 18 ) can be connected to enable the pivoting of the hub piece.
  • the set of levers 16 to 18 comprises at least three lever arms, one 17 of the lever arms being fastened by an articulation 21 to the body 3 , equally spaced from the steering knuckles on the different sides of the body, that is, between the steering knuckles on the different sides.
  • the articulation 21 does not necessarily have to be equally spaced from the steering knuckles, but in contrast to the figures it may be closer to one of the two steering knuckles.
  • the steering knuckles 4 , 5 are fastened to the body 3 by substantially vertical articulations 14 , 15 , and also the hub pieces 6 , 7 are fastened to the steering knuckles 4 , 5 by substantially vertical articulations 19 , 20 .
  • the articulations of the steering knuckles and the hub pieces are not vertical, in other words that they deviate from the vertical direction.
  • the actuators 12 , 13 driving the steering knuckles 4 , 5 can be fastened to each steering knuckle 4 , 5 concentrically by that articulation 19 , 20 of the hub piece 6 , 7 in the steering knuckle, by which the hub piece 6 , 7 is fastened to the respective steering knuckle 4 , 5 .
  • the actuators 10 to 13 are all fastened at one end to the body 3 ; in other words, they are supported by the body 3 .
  • the actuators 10 , 11 for driving the hub pieces 6 , 7 can be fastened to the respective steering knuckle 4 , 5 concentrically to that articulation 14 , 5 in the steering knuckle, by which the steering knuckle 4 , 5 is fastened to the body.
  • FIG. 2 a shows the operation of the steering mechanism according to the invention for steering the transport equipment, when the transport equipment is turned to the right (the initial travel direction of the transport equipment as well as the rotation direction of the wheels being indicated with an arrow).
  • the actuator 13 As shown in the figure, when one of the steering knuckles, i.e. the steering knuckle 4 on the right hand side of the figure, is pivoted by the actuator 13 about the articulation 14 , 15 arranged in the body 3 , the hub piece 6 therein, i.e.
  • the wheels can also be oriented parallel to each other, but there may also be a slight angular difference between them; in other words, they are thus not turned quite in the same direction, as can be seen in the figure.
  • FIG. 2 b shows the steering mechanism in a perspective view of the situation of FIG. 2 a , that is, when turning to the right.
  • the steering knuckle 4 on the right hand side is turned outwards from the body 3 ; in other words, it is turned counter-clockwise, by means of the actuator 13 .
  • the steering knuckle 5 on the other side of the body 3 is not pivoted; that is, it is placed against the body 3 .
  • the hub piece 7 in the steering knuckle is pivoted by the actuator 11 .
  • each steering knuckle 4 or 5 i.e. the one on each side, consists of at least two elongate pieces ( 4 ′, 4 ′′, 5 ′, 5 ′′) connected to each other by a connecting part 22 .
  • the connecting part can be, for example, welded between the elongate pieces.
  • Members for providing the suspension of the steering knuckle for example springs, can be fitted between the elongate pieces, but these are not marked in the figures.
